Abstract: Disclosed herein is a method for determining a resource area to be allocated to a bandwidth part (BWP) in a wireless communication system. More specifically, the method performed by a terminal includes: receiving, from a network, a first resource allocation field associated with a resource allocation group (RBG) size for a first BWP and a second resource allocation field associated with an RBG size for a second BWP, on the first BWP; and when the size of the first resource allocation field is greater than the size of the second resource allocation field, determining a resource area to be allocated to the second BWP, based on a value of the first resource allocation field, which corresponds to the size of the second BWP, starting from a predefined point.

Abstract: A method of receiving a Physical Downlink Shared Channel (PDSCH) includes: receiving, in a first bandwidth part (BWP), a downlink control information (DCI) including (i) first information that indicates switching an active BWP from the first BWP to a second BWP, and (ii) second information related to scheduling at least one transport block (TB) for the PDSCH; and receiving, in the second BWP, the PDSCH based on the first information and the second information. Based on a number of TBs in a first group of TBs that can be scheduled through the second information being equal to one, and based on a number of TBs in a second group of TBs that can be scheduled for the second BWP being equal to two: among the second information related to scheduling the at least one TB, information related to a second TB among the second group of TBs is disabled.
